SPECIFICATION forming part of Letters Patent No. 510,400, dated December12, 1893. Application filed March 13,1893- Serial No. 465,769- (Nomodel.)

To all whom it may concern.-

Be it known that I, JosEPH BODANI, of

7 Rochester, in the county of Monroe and State of New York, haveinvented certain new and useful Improvementsin Rocking-Chairs; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming apart of this specification, and to the reference-numeralsmarked'thereon.

My present invention has for its object to provide an improved springrocking-chair, which is simple and cheap in construction and not liableto get out of order, and to these and other ends it consists in certainimprovements in construction and combinations of parts, all as will behereinafter fully described and the novel features pointed out in theclaims at the end of this specification.

In the drawings: Figure 1 is a side elevation of a chair constructed inaccordance with myinvention; Fig. 2, a longitudinal sectional viewthereof; Fig.3, a cross-sectional view on the line 40-00 of Fig. 1.

Similar reference numerals in the several figures indicate similarparts.

The base of the chair indicated by 1 is preferably constructed of metal,stamped or otherwise formed with the supporting legs 2, and on the upperside with the vertically extending flange or portion 3 having a groove 4therein and belowv said flange with a supporting shoulder 5 on whichrests the lower edge of a turn-table or casting 6 encircling the flangeand prevented from vertical movement thereon by means of one or morescrews 7 entering the groove in said flange, as shownin Fig. 2. Upon theupper side of this turntable are two standards 8 and 9, the formerprovided with a laterally extending aperture 10 forming one of thebearings for a short shaft or axle 11 forming part of, or secured to, aseat-carrying plate or casting 12, upon which the top-board 20 issupported; the other end of said axle being journaled in a removablebearing piece 13 secured to the standard 9 by means of screws 15, thisarrangement permitting the ready insertion and removal of the plate 12to which the chair-seat is connected, as will be understood.

The top of the turn-table 6 is further provided with two sockets orrecesses 16 arranged on opposite sides of the shaft, adapted to receivethe lower ends of suitable volute springs 17, and the plate 12 to whichthe shaft is connected is provided on its under side with hemisphericalsockets in which operate balls or spherical projections 18 havingdepending portions 19 entering apertures 1n the upper ends of thesprings. These two sprmgs are about equal in force and serve to hold theplate 12 and the board 20 approximately horizontal and the occupant ofthe chair may rock back and forth on the axle, compressing one springand allowing the expansion of the other and may turn the chair on thebase to any position desired. The springs are so adjusted that extrememovement in either direction is prevented and the movement for a limiteddistance is very easy, but if des1red, suitable stops could be employedfor insuring only the proper operation.

It is, ofcourse, immaterial what form of top is applied to my improved,base and I therefore provide it merely with a top board 20 to which anysuitable chair-body, such as the one indicated by 21 herein, may besecured, as shown or otherwise, and though particularly adapted as abase for rocklng-chalrs, it could be used for other purposes, as Will.be understood.

Instead of making the base of sheet metal,-

as shown herein, the upper bearing portion could be made of metal andattached to su table wooden legs, and it is also immaterial that thebearing of the turn-table on the base be on the bearing portion 5, asshown, as it could as well be at top of the flange 3, or as I prefer tomake it in practice, it has a bearing at both of these places.

Chairs constructed in accordance with my invention can be made cheaply,and are capable of being knocked down and shipped in parts, if desired.

The spherical projections on the ends of the springs operating in therecesses in the under side of the casting carrying the seat, I findgives a very easy motion without excessive friction and though theprojections onthe balls fit loosely in the tops of the springs as thesprings are put in under tension they are not liable to becomedisplaced.

It is obvious that instead of having the shaft 11 rigid with theseat-board, it could be secured rigidly to the ends of the standards,and operate loosely in the part secured to the seat.

' The term casting is applied to the tnrn-ta ble 6 simply as adesignating term, as it is immaterial how it is constructed so far asthe operation of the device is concerned.

I claim as my invention- 1. In a chair, the combination with the basehaving the supporting legs and the casting swiveled thereon having theupwardly extending standards, of the seat-carrying plate pivoted on saidstandards having the sockets in its under side, and the springs on thecasting on opposite sides of the pivot having the spherical projectionson their upper ends engaging the sockets in the seat-carrying plate,substantially as described.

2. The combination with the casting having the upwardly extendingstandards, of the seat-carrying plate pivoted on the standards havingthe sockets in its under side and the springs on the casting having thespherical projections on their upper ends engaging the sockets in theseat-carrying plate, substantially as described.

3. The combination with the casting having the upwardly extendingstandards, and the recesses in its top, of the seat-carrying platepivoted on the standards having the sockets in its under side, and thesprings having the spherical projections engaging the sockets in thecarrying plate and supported loosely in the recesses in the casting,substantially as described.

4:- The combination with the casting havin g the stationary standard andthe standard removably connected to the casting, both havingcorresponding laterally extending apertures, of the seat carrying platehaving the shaft with the ends journaled in the apertures in thestandards, and the springs between the plate and casting on oppositesides of the shaft, whereby upon removing the movable standard the shaftcan be disengaged from the stationary standard by a longitudinalmovement, substantially as described.
